Minor ash emissions at Pavlof Volcano were observed by local observers and in web camera views yesterday evening from about 19:27-21:07 AKDT (3:27-5:07 UTC). The diffuse ash plume reached heights of 15,000-18,000 feet above sea level and did not travel far and remained in the general vicinity of the volcano. Since early last evening, the volcano has been relatively quiet and no additional ash emissions have been observed. Clear satellite views of the volcano obtained over the past day have not indicated any ash plumes or thermal signals until about 8:50 AM AKDT(16:50 UTC) this morning, when elevated surface temperatures were observed in satellite data.

Thermal signals at Pavlof are typically associated with lava effusion and it is possible that low-level lava fountaining may have been temporarily occurring this morning. Seismic activity remains elevated and above background levels. AVO will continue to monitor Pavlof closely as the present levels of seismicity indicate that the volcano remains in a restless state and additional ash emissions and lava effusion at the summit may resume with little or no warning.
